Local Environmental Conditions
This part of Santa Cruz is mostly open water, with some built-up land. Oak is the most prominent allergenic tree in the wider area, with hazel and cypress also present. Grasses, mugwort and plantain growing in the surroundings are the main non-tree sources of pollen. Mugwort is unusually common here compared with most other locations, making it a particularly important local pollen source.
Hazel and cypress open the pollen season in early spring. Tree pollen peaks in late spring, when the weather warms to around 15°C and oak is in full flower. Grasses take over in midsummer, with temperatures around 20°C, and their pollen lingers into early fall. The most intense period comes through summer, when mugwort and plantain are in flower.

How often is the Santa Cruz pollen forecast updated?
The Santa Cruz pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Santa Cruz come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Santa Cruz based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Santa Cruz, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
Understanding the Scale
The 0–100 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
